📝 Description of the bug

When I call solver.settings.setup.models.turbulence, an AttributeError is raised. This does not occur in Fluent Python console.

🔁 Steps to reproduce

import ansys.fluent.core as pyfluent
from ansys.fluent.core.examples.downloads import download_file
solver = pyfluent.launch_fluent()
case_name = download_file("mixing_elbow.cas.h5", "pyfluent/mixing_elbow")
solver.settings.file.read(file_type="case", file_name=case_name)
solver.settings.setup.models.turbulence.model = 'k-epsilon'

🎯 Expected behavior

The turbulence model should be set

💥 Actual behavior / traceback
